0d463ec19e tests: improve coverage for P2tr and AddressType (Leonardo Comandini)
Pull request description:
The new AddressType test shows addresses that are valid but have
no type. If in the future some of those get a type or become
invalid (either voluntarily or due to a regression), this will
highlight it.

55c627715f Moving globals into PSBT struct (Dr Maxim Orlovsky)
Pull request description:
I took the most non-invasive approach to reduce diff size. Many parts of the code can be improved in style or further refactored (like some functions are not necessary and can be just moved to be part of other functions), but I'd prefer to do that as a separate PR once this will be merged.
My approach with this PR:
1. Remove `Global` struct by moving its fields right into `PartiallySignedTransaction` - but keep the `util/psbt/map/global.rs` file with all its logic
2. Keep existing `Map for Global` implementation in the same file, but just change it to `Map for PartiallySignedTransaction`
3. With serialization, convert `Global` deserialization into crate-private function and use it from `PartiallySignedTransaction` deserialization
4. Refactor the tests and imports as required to get the thing compile and pass tests
The refactoring will be followed by PR(s) adding support for Taproot

Ambiguous TweakedPublicKey and UntweakedPublicKey type aliases and methods to convert
Use structs for Untweaked and Tweaked key type

Use type alias for UntweakedPublicKey
TweakedPublicKey::new(...) method added
minor naming and doc changes
Docs can always do with a bit of love.
Clean up the module level (`//!`) rustdocs for all public modules.
I claim uniform is better than any specific method/style. I tried to fit
in with what ever was either most sane of most prevalent, therefore
attaining uniformity without unnecessary code churn (one exception being
the changes to headings described below).
Notes:
* Headings - use heading as a regular sentence for all modules e.g.,
```
//! Bitcoin network messages.
```
as opposed to
```
//! # Bitcoin Network Messages
```
It was not clear which style to use so I picked a 'random' mature
project and copied their style.
* Added 'This module' in _most_ places as the start of the module
description, however I was not religious about this one.
* Fixed line length if necessary since most of our code seems to follow
short (80 char) line lengths for comments anyways.
* Added periods and fixed obvious (and sometimes not so obvious)
grammatically errors.
* Added a trailing `//!` to every block since this was almost universal
already. I don't really like this one but I'm guessing it is Andrew's
preferred style since its on the copyright notices as well.
This refactors `Script::bytes_to_asm_fmt`` function to use an iterator
instead of index. Such change makes it easier to reason about overflows
or out-of-bounds accesses. As a result this also fixes three unlikely
overflows and happens to improve formatting to not output space at the
beginning in some weird cases.
To improve robustness even better it also moves `read_uint`
implementation to internal function which returns a more specific error
type which can be exhaustively matched on to guarantee correct error
handling. Probably because of lack of this the code was previously
checking the same condition twice, the second time being unreachable and
attempting to behave differently than the first one.
Finally this uses macro to deduplicate code which differs only in single
number, ensuring the code stays in sync across all branches.

This clearly states lack of support for 16-bit architectures as well as
adds readable `compile_error!()` call. It also fixes a few stylistic
mistakes - headings (top-level should not be repeated) and missing
newlines.

This adds i686 to CI which can help catching pointer-size-related bugs

Opening a new PR seemed more appropriate than adding it to #658 I can change it if you disagree.

a0e1d2e706 Check for overflow in Script::bytes_to_asm_fmt() (Martin Habovstiak)
Pull request description:
This adds an overflow check in `Script::bytes_to_asm_fmt()` motivated by
`electrs` issue. While it was not tested yet, I'm very confident that
overflow is the cause of panic there and even if not it can cause panic
becuase the public function takes unvalidated byte array and reads
`data_len` from it.

~~Strangely, this breaks a test case and I can't see why. I'm publishing in case someone wants to help.~~
Edit: One damn character. :D Should be OK now.

This adds a test case for script formatting which caused overflow in the
past and a few others from the same "interesting" transaction. Note that
to trigger the bug one has to run the test on 32 bit architecture.

Pull request description:
Adds https://github.com/bitcoin/bips/blob/master/bip-0341.mediawiki message signature algorithm
The base is taken from `bip143::SigHashCache`, some code results duplicated but I think it's more clear to keep things separated
Would mark some bullet point on https://github.com/rust-bitcoin/rust-bitcoin/issues/503
Test vectors are taken by running d1e4c56309/test/functional/feature_taproot.py with a modified `TaprootSignatureHash` function to print intermediate values that I cannot found in the bip341 [test vector json](https://raw.githubusercontent.com/bitcoin-core/qa-assets/main/unit_test_data/script_assets_test.json)
UPDATE: Latest version includes the suggestion from @sanket1729 to create a unified tool for signature message hash for legacy, segwit, and taproot inputs. In particular, makes sense for mixed segwit v0 and taproot v1 inputs because cached values could be shared
